FAN COIL UNITS
Sizes 018, 024, 030
FEATURES
FF1D
The FF1DNA and FF1DNE Fan Coil units are designed as
upflow indoor air handlers for split-system heat pumps and air
conditioners. They are available with factory- or field-installed
electric heaters both of which include the disconnect. A fieldinstalled cooling control with disconnect is also available. A TDR
(Time Delay Relay) is included with either the electric heat or
the cooling control packages. The FF1DNE models are available with a factory installed TXV.
This fan coil may be installed free standing, wall hung or flush
mounted in the wall. The 22-in. wide cabinet size in all models
allows units to fit between standard stud spacings. No return air
ductwork is required if the application provides for return air in
the front of the cabinet through either a louvered closet door or
an optional accessory decorative grille panel.
The cabinet exterior is made of pre-painted galvanized sheet
metal. The cabinet is fully insulated to meet applications in conditioned space. Additional insulation is required if the unit is
installed in an unconditioned space. Unit is supplied with
replaceable filter.
Multispeed direct-drive PSC blower motors have been selected
to provide the proper air handling for both heating and cooling.
Motors are suspended at 3 points on rubber grommets for quieter operation.
All refrigerant lines, electrical power, and thermostat wiring
enter from the top of the cabinet. Sweat-type refrigerant connections on both liquid and suction lines make for swift, low-cost
installation. All service access to the unit is conveniently located
in the front.
The CHECK-FLO-RATER® piston ensures efficient and
dependable refrigerant metering, and eliminates potential service requirements of other metering devices. The CHECK-FLORATER® is located inside the unit, easily accessible for piston
maintenance or changeout.
In addition, units can be factory ordered with a hard shut-off
thermostatic expansion valve (TXV) metering device for performance improvement.
The drain pan is constructed of high-impact, sound-deadening,
corrosion-proof polyester resin. Primary and secondary drain
connections exit from the bottom or either side of the cabinet.

NOTE: Rough-in dimensions are 38-1/4 x 22-1/4 inches.
CLEARANCES
A minimum clearance of 21 in. is required in front of the access panels for servicing. Please note that this clearance is recommended
for servicing only. Installation clearances from combustible materials are: 0 in. from cabinet and supply-air duct (plenum included).
Leave adequate room for the condensate pan and refrigerant line connection.
NOTE: 22-3/4 to 24-in. on-center between-studs and 38-1/8 to 36-3/4-in. top-to-bottom inside-studs spacing.

† Use copper wire only. Use 75°C in this application. When using non-metallic (NM) sheathed cable, wire size required should be based on that of 60°C conductors, instead of wire sizes shown in table above per NEC 1996 Article 336-30. Length shown is as measured 1 way along wire path between unit and
service panel for voltage drop not to exceed 2%.
